present invention relates to means forinsuringthe ignition of'the'fheating fuel in an oil'burner .mech-anism and, among the objectsthereof, are to provide'ia construction such that the disintegrated fuelwillbe exposed to heat overa' larger area than has heretofore beencustomary in this art; to provide a device of the class indicated inwhich a plurality of igniting flames will act through a l 3 oconsiderable'area to cause an ignition of the fuel which it is desiredto ignite; to provide an improved device for the purpose indi-* cated;to provide an improved method of ignitingfiuid fuel and such furtherobjects,

7 5 advantages and capabilities as will here- 1 after appear'andasareinherent in the construction disclosed herein.

,My invention further resides'in the combination, construction andarrangement of, parts illustrated in the accompanying drawing and, whileI have shown therein what is now considered the preferred embodiment ofmy invention, 'I desire the same to be understood as illustrative onlyand not as limit- In the drawing annexed hereto and forming a parthereof, Fig.1 showsa plan view of theignition'means and air controlcollar which is to be installed within a furnace or 4 similar structurein which a fire is to be maintained; Fig. 2 is a transverse sectionofthe structure shown in Fig. 1, substantially along the plane indicatedby the line 2,2', Fig. 1; Fig. 3 is a fragmentary transverse section ofthe construction shown in Fig. 1, taken substantially alongthe' planeindicated by the line 3 3; Fig. 4 is a fragmentary transverse section'takenfsubstantially along the plane indicated by the line H, Fig 1 Fig,5 is a fragmentary sectional elevation showing my improved constructionin its relation to the burner mechanism and air control collarlandvalve.

Referring' more in detail to the'annexed' drawing, .numeral 1 denotesthe horizontal base portion of the venturi and numeral2 denotes the airring or collar rising'fromthis base, plate and serving to direct the airup Wardly against the under side of the rotating 1 head 3 by means of'whichthe oil is nebulized the furnace. Air'vanes 4. are secured to theunderside of the head 3an'd-extend'down- 'wardly along the shaft5'bymeans of which the head 3 is carried and r'0tated.--= An air.

is ;admitted through an-opening; 10 in the plate land moves to bothright and left, passthrough theextensions 11 and 12 of the channellandoutthrough openings 13 and 14 into the open. spacesl5 and -16 where itis ignited. It is notconsidered necessary in this' V instance todisclose the nieans wherebythe gasis ignited, it being sufficient tostat that such means is provided for thispurpose, f- An air deflectionring is formed, partly 'integrally with the air collar 2 and wall 7 asa'sthe upper surface of the part thereof which is integral'with thecollar 2 and walls 7,'thus forminga substantially continuous and uiiinterrupted upper surface,jwhen the device is assembled, this uppersurface being shown in Fig. l'wher'e'part 18 appears and directly shownat 17 and is partlyseparated there;v from,'as'shovvnat 18. This latter,at its in= P nercircumference, fits againsta shoulder 19 and rests uponal'edgeQO. Its ends rest upon opposite the same betweenthe,shoulders'Ql,the latter being designated by the numeral:

22'. The upper end of the throat or collar 2 is denotedhy' numeral 23and it is the outer face ofthis which forms the abutment 19 It will beobvious from the foregoing that the rotation of the head'S and vanes fwill drive air outwardly"tangentially, this air passing upwardlythrough. the c'ollar 2'and being regulated in amount by the position ofthe valve *meinher 6 with relation to" the throat or air collar. Thisair which is thrown ofitangentiall b the vanes 4 passes'over theupp'e'rsurface of the ring and'strikes the upwardly curved flange 24, whichforms a part of the ring 18 and is thus directed upwardly and outwardlytransversely of the fuel thrown off from the upper surface of the head8. It is thus thoroughly co-mingled with this fuel and is in propercondition to be ignited. Preferably sli 'htly before the beginning ofthe flow of oil the gas entering through-opening 10 and passing throughchannels 9, 11, 12, 13 and 14 is ignited in the compartments 15 and 16and burns therein. The mixture of air and oil which is heated over theopening 16 helps to raise the te mperature of the mixture over opening15 and ignition will therefore taken place here and work backwardly tothe opening 16. vThis gives'a sheet of flame between these two openingsand this flame, which results from the burning of the mixture of air andoil, is

intensely hot, as compared with the gas flame, This hot flame thereforeignitesthe mixture ofairuandvoil around the remainder of the circle.This flame between the openings 15 and 16, which may be termed gasnozzles, might be called a flaming are, on account of its length, whichis approximately 7 5 degrees- It will be readily understood that aflame'o'f this size will be more effective in producing ignition of themixture of the gas and oil than would asingle flame produced by oneofthe gas nozzles alone. It has been found in use that this device isextremely efficient injcausing ignition of the fuel in an oil burningheater.

It is of course understood that the specific V 7 description ofstructure and method set forth abovemay be departed from withoutdeparting from'thespirit of my invention as set forth in thisspecification and the appended claims. v

' It is intended to claim both broadly and specifically the variousnovel subjects mat ter disclosed herein and I therefore desire thatfailure to insert any claim commensurate with the scope of my inventionbe not construed. as an abandonment thereof.

Having now described my invention, I claim: v

1. :An ignition unit for oil burners comprising a base plate and aircollar, said air collar having a groove at its upper .end extending partway around the same, walls integral with the collar forming a gaschannel,

a gas admission part opening into said channel, a pair of gas burnersconnected with said channel at-separated points around the peri phery ofthe collar, and airing around the air collar 'and'resting in the grooveand supported by the collar. 7 V 2. An ignition unit for oil burnerscomprising a base plate and air collar, walls integral therewith forminga gas channel, a

portion of one of the walls forming a part of an air deflection ring, aportion of a separate ring cooperating with said surface to from oneside of the collar having a; gas

carrying channel therein and a port for admitting gasto said channel,and a pair of burners'connected with said projection and havingcommunication with the channel whereby gas is simultaneously admitted toor shut off from both burners, said burners including cups in whichcombustion may take place. i

In witness whereof, I hereunto subscrib my name to this specification.
